Pic De Médécourbe
Pic de Médécourbe (Catalan: ''Pic de Medacorba'') is a mountain in Europe that sits on the western tripoint boundary of Andorra, France and Spain. It is tall. It overlooks Étang de Soulcem, a large artificial lake used for hydroelectricity generation, and the :fr:Vicdessos (rivière), Vicdessos valley.Govern d'Andorra (1991). ''Atlas d'Andorra'', map of northwestern Andorra, p.20. There is also an eastern tripoint of Andorra, France, and Spain approximately 6 km south of Pas de la Casa. Geological and glacial history Geological studies and glacial research conducted in the Médécourbe valley, which lies directly north of the mountain, reveal a rich history of glacial activity dating back to the Late Glacial and Holocene periods. Moraine landforms in the upper Médécourbe valley provide evidence of past glacier advances and retreats. In particular, large moraines formed around 12,400 years ago, during the transition period between the Late Glacial period and the Younger ...

Surface Exposure Dating
Surface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows, meteorite impacts, rock slides, fault scarps, cave development, and other geological events. It is most useful for rocks which have been exposed for between 103 and 106 years. Cosmogenic radionuclide dating The most common of these dating techniques is ''cosmogenic radionuclide dating''. Earth is constantly bombarded with primary cosmic rays, high energy charged particles – mostly protons and alpha particles. These particles interact with atoms in atmospheric gases, producing a cascade of secondary particles that may in turn interact and reduce their energies in many reactions as they pass through the atmosphere. This cascade includes a small fraction of hadrons, including neutrons. When one of these particles strikes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-thousanders Of France
Two-thousanders are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: ''Zweitausender''). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain. The Säuling (top) is a prominent, individual peak, whereas the Schneeberg (bottom) is an elongated limestone massif. In ranges like the Allgäu Alps, the Gesäuse or the Styrian-Lower Austrian Limestone Alps the mountain tour descriptions for mountaineers or hikers commonly include the two-thousanders, especially in areas where only a few summits exceed this level. Examples from these regions of the Eastern Alps are: * the striking Nebelhorn (2,224 m) near Oberstdorf or the Säuling (2,047 m) near Neuschwanstein, * the Admonter Reichenstein (2,251 m), Eisenerzer Reichenstein (2,165 m), Großer Pyhrgas (2,244 m) or Hochtor (2,36 ...

Border Tripoints
Borders are generally defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas. Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. For the purposes of border control, airports and seaports are also classed as borders. Most countries have some form of border control to regulate or limit the movement of people, animals, and goods into and out of the country. Under international law, each country is general ...

France–Spain Border
The France–Spain border was formally defined in 1659. It separates the two countries from Hendaye and Irun in the west, running through the Pyrenees to Cerbère and Portbou on the Mediterranean Sea. It runs roughly along the drainage divide defined by the Pyrenees, though with several exceptions. Features Main border The Franco-Spanish border runs for between southwestern France and northeastern Spain. It begins in the west on the Bay of Biscay at the French city of Hendaye and the Spanish city of Irun (). The border continues eastward along the Pyrenees to the sovereign nation of Andorra (). At this point, the small country interrupts the border between Spain and France for on the Spanish side and on the French side. Then the border continues eastward () to the Mediterranean Sea at Cerbère in France and Portbou in Spain (). From west to east, crossing the border: Llívia Spain has an exclave in France, Llívia, in the Pyrénées-Orientales. Pheasant Island Ne ...

Andorra–Spain Border
The border between Andorra and Spain is in the Pyrenees between northern Spain and southern and western Andorra. It is long. It is an external border of the EU, as well as an external border of the Schengen area, as Andorra is neither part of the EU nor a party to the Schengen agreement. Specifications The Spanish-Andorran border runs between the south of Andorra and northern Spain (by the autonomous community of Catalonia) in the Pyrenees Mountains. Because both Spain and Andorra are situated in the same watershed, travel is easier (roads are better) than travel between Andorra and France. The sole official language of Andorra is Catalan. The border begins in the west at the Andorra-France-Spain tripoint (). It then follows a generally south-eastern direction, later turning northeast to the eastern Andorra-Spain-France tripoint (). The dividing line between the two countries goes through high mountain areas, often over , and passes close to the highest point of Andorra, the ...

Andorra–France Border
The Andorra–France border extends for in southern France (Ariège (department), Ariège and Pyrenees-Orientales Departments of France, départements) and northern and north-eastern Andorra. The border is France's third-shortest, after its borders with Monaco and the Kingdom of the Netherlands (the latter on the Caribbean island of Saint Martin (island), Saint Martin). Specifications The border's western extremity starts at the western Andorra–Spain–France tripoint, located at the summit of the Pic de Médécourbe (42°36'13"N 1°26'33" E). It then follows a general north-east direction before switching south-eastwards to the eastern Andorra–Spain–France tripoint 42°30'09"N 1°43'33" E). Most of the Franco-Andorran border is determined by custom – there is no international treaty formally fixing the course of the border, except for the cases below. In 2001, a bilateral treaty between France and Andorra rectified and amended the border slightly. It provided for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains Of Occitania (administrative Region)
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...
